My original polysomnography showed 1 obstructive apnea, 1 central apnea, 2 hypopneas and 148 respiratory effort-related arousals in 6 hours of sleep, with greatly increased stage 1 and significantly decreased stage 3 and REM sleep, so I think UARS fits. However, the 2
titration studies I had seemed to have been focused on apnea; the CPAP pressure used only reduced my RERAS to 12/hr hour, and the sleep fragmentation was worse than my diagnostic study.
